Packaging Error Using AIR 28

Love the progress with AIR 28, kudos to the AIR team!

All is well using the simulator and packing for Android - however, using FB and packaging for iOS Development, Ad Hoc or Production - I'm seeing the following error:

unexpected failure: multiple points

java.lang.NumberFormatException: multiple points

This may be to do with necessary pList info keys or APP icons mentioned in the AIR 28 release notes - so working through that now and will post back if I resolve this - otherwise any help much appreciated.
